Incompatible with Windows 8 before update (requires Windows 7 and several Yoga sessions)

After a technical error loop with the Intel WiDi software on Windows 8 (can not connect), it turns out that it is necessary to update the product to use it (according to testimony on technical forums) ... of course, this is only possible with Windows 7, so the snake biting its tail.

I still made the effort to install a temporary version of Windows 7, just for the update.
Despite neat installations, relocations, and other technical detours (safe mode, etc.), I encountered an obscure essential software error ("Unable to launch Intel MyWifi"), which, however, never appears in Windows 8.

I ended up dropping (though it's not my style).
I got reimbursed the product, and bought for 7, HDMI cable 10 meters that worked right away. To say that I had spent 70 in the ScreenCast ... and he now costs more than 120!
